Like lavender, tea tree is a must for the first aid box. One of few oils that can be used neat on the skin. Excellent for cleaning cuts, bites and grazes.
Tea tree can be applied neat on a cotton bud to spots and boils. It has a very strong antiseptic, antibiotic action, helpful treating infected acne (with great care as it can strip the skin). It is also good for treating thrush(2-3 drops added with a little milk to a sitz bath) and athelete's foot (add a few drops to a bowl of water and soak the feet for upto 10 minutes)
